A brewing cartridge containing a filter containing brewing material and configured to reside generally horizontally in a coffee maker. The filter has a top rim sandwiched between a coffee holder cover and a coffee holder base, and the cartridge may be disassembled after use to recycle and/or reuse components thereof, the rim facilitating removing the filter and brewing material from the used cartridge. The coffee maker includes a reservoir, a pump, a heater, and a nozzle for injecting heated water into the cartridge. The cartridge receives the heated water through the coffee holder cover and releases brewed liquid through a passage on a side of the cartridge. The cover may be a plastic cover or a foil cover, and the filter may be provided to a consumer as an empty filter for filling by the consumer, or as a pre-packed filter containing brewing material. |
